2. GE’s 2.3-107 Wind Turbine
GE’s 2.3-107 wind turbine is an advanced evolution of the 1.x series, providing a 30% increase in Annual
Energy Production (AEP) over its predecessor, the 1.85-87. Engineered for medium wind speeds, the 2.3-107
provides a 51% increase in swept area and an extra 350 kW output at rated wind speed compared to
the 1.85-87 turbine, improving project economics for wind developers. GE’s proprietary Advanced Loads
Control combines drive train sensors with Mark* VIe turbine controller capabilities to individually pitch
blades and improve loads handling performance.
GE’s stringent procedures result in a turbine engineered for high performance and availability. The use of
select components from both the 1.x and 2.x platforms provide the consistent workhorse performance and
reliability that GE wind turbines are known for. The 2.3-107 utilizes the same drivetrain and electrical system
architecture as GE’s 1.x series, with both systems scaled and upgraded to provide improved performance
along with greater wind turbine energy production. Other critical components have been scaled from the
existing platforms to meet the specific technical requirements of this evolutionary turbine.
Providing consistent workhorse performance, reliability and efficiency, GE’s new 2.3-107 meter wind turbine
is an advanced evolution of the 1.x platform wind turbine series, scaling and developing 1.x platform
electrical system upgrades to increase the rating of the turbine from 1.7 MW to 2.2 MW, allowing higher
energy production.
Building Upon the Proven
1.x and 2.x Platforms
The evolution of GE’s 1.5 MW turbine began with the 1.5i turbine introduced in 1996. The 65 meter rotor
diameter turbine soon was increased to 70.5 meters in the 1.5s, then to 77 meters in the 1.5sle turbine
that was introduced in 2004. Building on the exceptional performance and reliability of the 1.5sle, GE
introduced the 1.5xle with its 82.5 meter diameter in 2005. Subsequent improvements led to the introduction
of the 1.6-82.5 turbine in 2008—followed by the 1.6-87 in 2011, and ultimately the 1.85-82.5 and 1.85-87 in
2013. Built from the maturity of its predecessors, the 2.3-107 evolution provides increased capacity factor
while increasing AEP and application space.
Significant component enhancements to the 1.x models have resulted in a substantial performance increase,
enabling the use of a 107 meter rotor on the 1.x series, and an uprate to 2.2 MW. These enhancements include:
larger bedplate, generator frame and gearbox; controls improvements, and enhanced power conversion
capabilities resulting in an increase in nameplate and AEP. Configured for high reliability, GE’s 2.3-107 can
provide excellent availability, comparable with the 1.x series units operating in the field today.

3. Construction
Towers: Tubular steel sections provide a hub height of 80 meters
Blades: GE 52.2 meter blades
Drivetrain components: GE’s 2.3-107 uses an enhanced gearbox, main shaft, and generators
with appropriate improvements to enable the larger rotor diameter in medium winds
Enhanced Controls Technology
The 2.3-107 wind turbine employs GE’s patented Advanced Loads Control. This feature reduces loads
on turbine components by measuring deflections and individually adjusting blade pitch.
Condition Monitoring System (option)
GE’s Condition Monitoring System (CMS) and SCADA Anomaly Detection Services, a complementary
suite of advanced condition monitoring solutions, proactively detect impending drive train and
whole-turbine issues enabling increased availability and decreased maintenance expenses. Built
upon half a century of power generation drivetrain and data anomaly monitoring experience, this
service solution is available as an option on new GE units and as an upgrade.
Technical Description
GE’s 2.3-107 wind turbine is a three-blade, upwind, horizontal axis wind turbine with a rotor diameter of
107 meters. The turbine rotor and nacelle are mounted on top of a tubular steel tower, providing a hub
height of 80 meters. The turbine uses active yaw control to keep the blades pointed into the wind. The
2.3-107 wind turbine operates at a variable speed and uses a doubly fed asynchronous generator with
a partial power converter system.
Specifications:
2.3-107 Wind Turbine:
• Engineered to IEC 61400-1 ed3, Class IIS
